摘要： A code sequence made up multiple instructions and specifying an offset from a base address is identified in an object file. The offset from the base address corresponds to an offset location in a memory configured for storing an address of a variable or data. The identified code sequence is configured to perform a memory reference function or a memory address computation function. It is determined that the offset location is within a specified distance of the base address and that a replacement of the identified code sequence with a replacement code sequence will not alter program semantics. The identified code sequence in the object file is replaced with the replacement code sequence that includes a no-operation (NOP) instruction or having fewer instructions than the identified code sequence. Linked executable code is generated based on the object file and the linked executable code is emitted.

摘要： Compiling code for an enhanced application binary interface (ABI) including identifying, by a computer, a code sequence configured to perform a variable address reference table function including an access to a variable at an offset outside of a location in a variable address reference table. The code sequence includes an internal representation (IR) of a first instruction and an IR of a second instruction. The second instruction is dependent on the first instruction. A scheduler cost function associated with at least one of the IR of the first instruction and the IR of the second instruction is modified. The modifying includes generating a modified scheduler cost function that is configured to place the first instruction next to the second instruction. An object file is generated responsive to the modified scheduler cost function. The object file includes the first instruction placed next to the second instruction. The object file is emitted.

摘要： A mechanism for minimizing effective memory latency without unnecessary cost through fine-grained software-directed data prefetching using integrated high-level and low-level code analysis and optimizations is provided. The mechanism identifies and classifies streams, identifies data that is most likely to incur a cache miss, exploits effective hardware prefetching to determine the proper number of streams to be prefetched, exploits effective data prefetching on different types of streams in order to eliminate redundant prefetching and avoid cache pollution, and uses high-level transformations with integrated lower level cost analysis in the instruction scheduler to schedule prefetch instructions effectively.

摘要： Embodiments of the present invention address deficiencies of the art in respect to nested transaction rollback and provide a method, system and computer program product for dynamic nest level determination for nested transaction rollback. In an embodiment of the invention, a nested transaction rollback method can be provided. The method can include detecting a violation of a block of memory accessed within a set of nested transactions, retrieving a tentative rollback level for the violation, discarding a speculative state for the block of memory at each level of the set of nested transactions up to and including the tentative rollback level, refining the tentative rollback level to a lower level in the set of nested transactions, and additionally discarding a speculative state for the block of memory at additional levels in the set of nested transactions up to and including the refined rollback level.
